To all whom-152? mqy eoncem Be 1 known that 1, DAVID E. GRAHAM? a ,.citizen of the United. States, residing ale *Br'stul, oouiity of Hartfox-d, State of Conyjneetieut, have invented a certain new and useful Antiincfiion-Bearmg, of Winch the following is a full, clear, and exact descriplion, such as will enable others skilled. inihe ml; to which it eppelttains to make and use the same, reference being heclto the accompanying drawings, forming part; of this specification. v

Ely inventien relates to anti-friction bearingd, and mere particularly to the separator fer the bells or other anti-friction-members of a bearing embodying two such rows. In

se-Qcellerl double row bell bearings it lms beeneustomery to employ a unitary separeter having pockets or recesses n its Opposite.

edges for receiving the balls of the respecfive rows. But in some instances this has proved unsatisfactory. It 13 practically .impossiole to produce'reces of exeeely the same diameter for each row of bells. Therei'ere, 1t frequently happens that in e double row bearing one rew of bells tends to travel faster then the ooher row, and the result is ihei; the unitary separate? engaged bot-h rows of ioalls is held back by engagement with the slower row While the balls of the faster row pressegainst the sepei etor in their effort to travel about the centei" of retaeion of the hearing. The sepa 'ator thus becomes jammed between the halls of the two rows and, consequently, interferesiviih illfree rolling of the balls, Frequently the balls thus jammed weer away the pocket Walls of l lieeeperetoig and in some instances the strain (senses the separator to break all) M? object is to provicle a structure in wliioli the balls of v erly epaeed or separated and yet each row can rotate independently of the citizen A further abject is to provide a separator which permits the accomplishment of the object just above recited.

To these encls, end'eleo to improve generally upon devices of the character inclieatecl, my invention eonsists in the various matters hereinafter elesc ribecl and claimed.

In the accompanying clrawings: Figure 1 is 1 sectional elemlien of a bearing emboiying my invention; Fig. 2 is an elevation, partly 1n section on about the lme .Z LZ of Fig. 1, looking in the direction oi? the arrows,

we row are held prop all but three of the balls being removed: and Fig. 3 is a sectional elevation of the separator alone, his sections being shown spaced from each other.

In saicl drawings, represents the inner rnee'member, l1 theeuter race-member, M and. the balls ml'eellsets 0f the respec tive ewe rows between said moo members, and 18 the separator. The inner race-member is ,illuetreted as a, sleeve or supporting member having the separated circumferential ball grooves 01' ifaees 12 and 13, While the outer race-member is shown as anennulus com prising the eup-rings 520 and 2]. held together by else easing ring-2 lto move as a single ele- Miem,

The separator is splitand comprises the separate rings or separator-sections and 32. Each eepai'aiot-seetion can be lermei a separator. Each oftliese separafuor-seciions lies recesses or pockets 19- in [is outer edge to receive the balls of the apprepriete row, and eachseiii ring also has a, ielniively breed, ilet inner 20532 which abuts a g'ainst the corresponding face oi the coii-peraeing ring. T me, each separator section can rotate independently of the other,

so elm eli' row oi balls can romie at its own ieezi "filillfllllldetriment to the other againsteeeh other and almost filling the space beiween the rows of balls, are seom'elv held against wzibliling and displacement. v

in the illuem-zited embodimentef my invention, envll sepzuzatowsoeiion is made of a single plea; of "relatively thin metal and has a flared pmri'iion 215 in which the Saki peekefs 13 are iomiei L each szii ll section elso lmving :1 flange 3:? which :iilm'ds the said relatively broad llblliill'lg-filml 3B: The lull-engaging member or flared. poiiien is disposed engulzirly relatively to the axis 0i its travel. These separator SBCijlOD can be szluinperi and:- eceupy hue li hiie spzu'e. Thus, by my present ii n' niion each rew of balls of a double row bearing; can rotate at its own speed without (l2 to the other balls or to the separator, and the separate;ie-securely held against "webbling or other imclesimble displeeemenl the separator occupying butsnmll some and being easily and inexpensively pz-ocluced.

liming iiill'iS described my invention, What I claim as new and desire to secure by Letters Patent is 1. The combination With a supporting member having a pair of separated race- Ways, an annulus havinga pair of raceways cooperative with those of the supporting member, and a pair of ball-sets in the raceways in the supporting member and annulus, respectively, of a pair of flared separators for said ball-sets, respectively, and having at their adjacent faces flanges contacting with each other for guiding both separators for independent free travel with their ballsets, respectively.

2. The combination with a supporting member having a pair of separated race- Ways, an annulus having a pair of raceways cooperative with those of the supporting member, and a pair of ball-sets in the raceways in the suppporting member and annulus, respectively, of a pair of separators cooperative With said ball-sets, respectively,

each separator having a ball-engaging member disposed angularly relatively to the axis of its travel, and contacting With each other for guiding each other for independent travel relatively to each other.-
